2

Set a master password

Create a master password to encrypt all sensitive data (private keys, API keys, settings) stored locally on your machine. You can also choose Continue without encryption, but this is not recommended.
All data is stored locally — Oxygen Atmos does not send your keys or credentials to external servers.

​
Auto-updates

When a new version is available, you’ll see an in-app notification. To update, restart Oxygen Atmos.

​
Reset application data when the vault is locked

Oxygen Atmos does not store or recover your master password. If the vault is locked and you cannot unlock it with the master password or PIN, click Forgot password? and follow reset the app.
Locked vault with the reset application option
